This blog is a follow up on the Conduit Run Lengths Blog.
Although the Conduit Run schedule includes the lengths of the runs including elbows, it doesn't separate them out.
If you want to be able to schedule the elbows there is a bit of modifying that we need to do in the conduit elbow family to get this to work.
In my example I am using the OOTB Conduit Elbow - without Fittings - EMT.rfa family.
Objective
We need to add some shared parameters and some formulas so that we can end up with a schedule like this in our project.
Editing the Family
Open the family and save it into your custom library.
On the Create tab, open the Family Types dialog.
Add the following shared parameters (instance) and group them according to your preferences. It is also handy to add a Tool Tip for them and this needs to be done when you create them. All will be length parameters with the exception of the Elbow Angle which will be an angle parameter. I grouped mine all under the Data category simply because it separated them from the built in parameters, you can group them where you feel it is appropriate.
- Elbow Angle
- Allows us to schedule the elbow angle
- Bend Length
- Calculates the length of the elbow bend portion only at the outside radius
- Bend Outside Rad
- Calculates the bend radius plus the fitting outside radius to give us the correct outside radius value
- Bend Rad
- Allows us to schedule the Bend Radius
- Elbow Outside Length
- Calculates the entire length of the elbow segment based on the outside radius and the angle of the elbow
Once we get all of these added to the family, type in the formulas shown below.
Now we can load this into our project or template and build the schedule.
Use the Conduit Fitting Category Schedule and add the fields shown in the first image.
IMPORTANT NOTE
If you change a run from one size to another it does not change the bend radius value to what it would have been if you drew the run from scratch.
